Fixed Inductors

Inductors are electrical components that store energy in the form of an electromagnetic field. Fixed inductors are devices that have their inductance fixed or preset at the time of manufacturing. Inductors have a variety of uses, such as filtering, power conversion, matching, and impedance transformation. The 5022R-911H is a fixed inductor that can be used in a variety of applications. This article will discuss the application field and working principle of the 5022R-911H.

Application Field

The 5022R-911H is a type of cast iron-cored fixed inductor. This type of inductor has a wide range of uses. The 5022R-911H is an excellent choice for applications where high power efficiency, low leakage, and low temperature coefficient are desired. It is typically used in power supplies, switching converters, DC-DC converters, and high-voltage circuits. Additionally, it can be used in a variety of other applications, including bleeder and RF circuits.

Working Principle

The working principle of the 5022R-911H is based on Faraday’s law of electromagnetic induction. This law states that when a conductor is surrounded by a changing magnetic field, electric current is induced in the conductor. The current generated is proportional to the rate of change of the magnetic field. An inductor works by storing energy in the form of a magnetic field when a current passes through it. When the current is switched off, the magnetic field collapses, causing a reverse current to be generated, which is known as inductive kickback. The 5022R-911H consists of a cast iron core, a coil, and two electrodes. The core provides a path for the magnetic field to flow through, while the coil stores energy in the form of an electromagnetic field.

Advantages

The main advantage of using a fixed inductor such as the 5022R-911H is that it eliminates the need for external capacitors and resistors. This makes the circuit simpler and more efficient, which in turn results in improved power efficiency and less leakage. Additionally, the magnetically shielded enclosure reduces noise and protects against external interference. The 5022R-911H also features a low temperature coefficient, which ensures that the inductor performs reliably over a wide range of temperatures.

Conclusion

The 5022R-911H is a high-efficiency fixed inductor that can be used in a variety of applications. Its cast iron-cored design provides excellent high power efficiency, low leakage, and a low temperature coefficient. Additionally, it eliminates the need for external capacitors and resistors, making the circuit simpler and more efficient. This makes the 5022R-911H ideal for applications such as power supplies, switching converters, DC-DC converters, and high-voltage circuits.
